stated that a similar change in sexuality had been observed in a 
new hybrid Begonia raised in France, and that the origin of ^e- 
ffonia fri^ida, which, bears hermaphrodite flowers, is unknown. 
Mr. Berkeley brought a leaf of Ficus reticulata given him by Dr. 
Carter, with supplementary leaves springing from the under sur- 
surface. He also brought from his garden succulent stolons from 
Mimulus moscJiatus which appear not to have been previously 
observed. 
Leaves of a beech with galls were sent, which have since been 
ascertained to be the produce of Cecidomyia fagi. 
Mr. Blenkins brought specimens of Cynosmorium coccineum. 
Mr. A. Murray exhibited specimens of a Lady-bird belonging 
to the genus Epilachna sent to Mr. Masters by M. Naudin from 
Collioure ; also a Coccus from Guatemala used to colour wood 
of a grey-rose colour. 
Dr. Moore sent a Teazle from Glasnevin, with a spirally coiled 
stem, the leaves being alternate instead of opposite. 
Dr. Masters brought a Eeport of the observations on the action 
of manure at Chiswick in 1871, which will be published in the 
Journal. 
The Meeting then adjourned. 
GENEEAL MEETING. 
James Bateman, Esq., F.E.S., in the Chair. 
Mr. Berkeley, commenting on a fine cone-bearing branch of 
of its parent species, which are all monoecious. I have succeeded in preserving 
one plant only of this cross. I have somewhat analogous experiments among 
the above tribes yet waiting to be tested. 
" One other thing I wish to refer to is a singular tendency I have observed in 
some plants (creepers) to repel or withdraw from the contact of others. I have 
an Ampelopsis Veitchii running up a tower, apparently to avoid a Pyracantha 
running up alongside of it. The natural tendency of the former (both on a 
west aspect) I thought should have been to the sun ; whereas, as if to escape the 
latter, it tends to the north. I pointed it out to my neighbour, Col. Ranken, 
to-day ; and he said he had heard something of the same kind as regards the Ash 
tree, and that certain other trees grew away from, as if repelled by it. On the 
other hand, I have on a wall adjoining the tower Ivies running up, which, where 
originally apart, seem, as the shoots grow up, to attract each other. Has any 
such law as that of attraction and repulsion been observed in plants ? Can there 
be any such law ? "
